HARROW.

SPEGIIEICATION forming part of Letters Patent N0. 256,619, datecl April 18 1882. Application filed January 31, 1881. (N model.)

T0 all whom z't may oolzcern:

Be it known that I, JAMES H. BARLEY, of Sedalia, in oho couuty of Pettis and Stalo of Missouri, have invented oertain new and useful Improvements in Harrows; and -I (lo bereby deolare the following to be a ful], clear, ancl exaot1 desoription of the invention; such as will ena-ble others skilled in the art to which in pertains to make and use it, reference being had to the aooompanying drawings, which form parl: of this specification.

My invention relates t0 an improvcment in harrows; and ib oonsists- First, in atbaohiug the seolions ofthe harrow to a single draft rod or bar by .meaus ofchains, whioh have their rear onds fastened to the oorners of eaoh seobion, which seotionsare connected together by meaus of diagonal brace-rods or ohains, and by shorb clrains, whioh are fastened t0 the overlapping ends of the rods which couneel: thefront euds ofthe beams together, and which ohains are fastened to the chaius whioh are fastened to the draft rods or Uars, as will bo more l'ully descrlbed hereinafter. lho ob- 2 jeot 0f this part ot' my, invention is to couneot the sections of tl1e harrow together by means of a drafn i1ttaol1ment which rendors the harrow-seotious more easily turned at the oorners without oramping, ancl which efieotually proveuts tl.1eir rear ends fromm swinging and olosing in upon eaoh other when an ob stacle 0r rough ground is enoountered.

Second, in making eaoh beam of tho section of the harrow out ot' double-flanged iron, and securing tl1e harrowteeth against tl1e sides or edges of these beamsin such a manner {hat they can be adjusted to stand ve'rtioally to the side of the beam, or ab anydesired inelination thereto, aooording to the direotion in whioh the harrow is drawn. Tl1e objeot ofthis part of my invention is to devise a means for making the harrow-teeth akljustable againsb the sides or edges of the double-flanged beams, instead of havlng the"teeth pass vertiea-lly -up through both 0f the fianges, as l1as heretofore been the oase, and thus enable 'rlxe teeth to be used in two 01 more positions, instead of only one.

V Figure 1 is a plan view of myin\"e ntion complete. Fig. 2 is an edge view of the same. Fig. 3 Shows a side and a vertical seo'ion of one method of securingthe teet h t0 the beams by means of an eyobolt anr'la block whioh lS plaoed in between the two fianges. Fig. 4

shows Sirailar views, with the difference that tl1e tooth passes (low;n througln the block itself, instead of through the eye made in the olamping-bolt. Fig'. 5 shows tl1e olampingblooks secure l rigidly in position between the two flanges of tl1e beam und tho teeth allowed to move back and f'orth i n the block. Figs. 6 an(l 7 are detail views of the extenslon on toe front end of the harrow;

A represents a Single coutiuuous drall; rod or bar, to whioh the sections B of tl1e harrow are seoured. Bach one of tho seetions of the harrow is fdrmed of three or x'nore doubleflanged beams, O, whiolx are united together at their rear ends by 1neans ofa oross-bar, D or by a nnmber of olamping-bolts, 'on whioh are plaoed the spools a, fo r keeping the ends of tl1o beams the same distance apart. The fronl; ends of.the beams' are secured together by means ot' the ba-1s E, w'uioh overlap the sectlons bat slightly ab one corner, but (l0 everlap oonsiclerably at the other. Aoross the top of euch seotion is seourecl a brace,li, whioh has its front end l'astened to the overlapping rightband end of the eonneoting-rod E. These two cross conn eotingmods und the braoe may be mado of double-flanged iron similar t0 the beams, o1" ot' flat rods, as may bo desirled.

Eacl1 seotion ofthe harrow is connected at its left-hand corner to tl1e draft-rocl A, by 1'neans of a chain, G, whioh has its rear end fastened t0 the overlapping ond of the cross-rod E, and then the seotions are oonneot'ed together by means 0f the diagonal rods, braoes, or ohains H, whicl1 have tl1eir rear euds f'astened ab or near the oenter. of one seotion and their freut ends fastened in 'the overlapping end of the cross-rod E.-

Instead of the chains G, a rod having its end clivide d into two prongs may be used.

All of the seotions exoepb the right-band one,

are oonnected at: their right-hand ooruers by a ohaln, I, with tho l1ains Whioh are fastened direotly to the draft-rod. By means of this oonstruotiou euch seotlon of the harrow is so oonnected to the adjoining one that; they cannot; possibly clo se upon eaoh ot'her als their rear ends when an obstruction 01" rough ground is reaohed, as they otherwise would (10, u-nless some special provisiou is made topreventthem.

T0 the lefc oorner of the left; seotion, insteacl of a chain being used to oonneob in with the draft-rod, a single rigid link is used, so as to hold this secfiion more firmly and rigidly in positlon, and thus prevcnt in from swinging around toward thc draft-rod, as lt; would do, having nothing to counterbnlance it; on its outcr side. 'lhe scctions of the harrow beiug thns conncctcd together and to the draft-rod, 110 one of then1 can be moved latcrally Without aflecting the others to an equal degree.

The overlaiming extensions o1 the bar E can be madc, whcn nrcfcrrcd, by passing a rod of iron through holes formed throngh thc sidcs of the beams, and throngh spools or blocks which go bctwccn said bcznns to hold thc1n thc desired distance apart.

011 the right-hand front sldc of euch cnd of each section a short block can be placed on the outside cnd of thc clamping cross-rod, thns forming the projeclion the san1e as when the cross-bnr is bolted across the top of the beams of euch scction.

I am zuvare that heretofore wlde channcl er U-shaped metal bcan1s, similar to what are shown, havc been nsed in harrows; but thc teeth have always bccn passcd np through both flangcs, and thus hold rigidly in Position, so that they are capablc of use in hat; a single position only. One of thc special features of my invention is to so connect thcse tceth to the sides of the bean1s (hat they cnn be used in two o1 more dlffercnt positlons.

In Fig. 3 is shown a block, J, having two of its diagonnlly-opposice corners cut awny, und then itand the tooth are clamped to 1he side of thc benm in betwccn the two flanges, as shown. Asthetwodiagonally-oppositecorncxs ot' thc block are cnt away, the block and teeth tnrn upon the bolt, and the flangcs act as stops so as to llmi the movcment of the blocks and thus the angle ab which thc teeth shall be inclined. 'Ihe angle ut whleh the tceth shnll bc inclined to the side ol' thc bcam is regulatcd b y the amonntwhich is cnt from the corners ot the blocks. In Fig. 4 is shown a similm block with this exceptlon, that the holt; asses simply throngh the block am]. the bea1n, and the block is provided wilzh openings through its onter edges, down t.hrough which thc tooth is passed. In both of the above cascs the clamping-bolt acts as o pivot npon which the block und thc tooth move, and thc tooth will stand vertically to the side of the beam or be inclincd backward, according to which end cf the hmrmv is first drxuvn forwnrd.

In l ig. 6 a block, Y, is clampcd 1lgidl3' to the sidc cf thc beznn in betwccn thc flanges, and which has an opening made throngh in sufficiently lnrgc for the tooth to play back und. forth, as shown. 'lbc inncr sidc of this block is made thickcst ab its cente1, so as to bcar against thc tooth at (bis poinl; onl y and thus servc as thc plvol; upon which the tooth moves. Ehe opcning through thc block is of such a shape that the tooth will be hold vertically to the sidc of t.he bcam whcn one end of the harrow is dmwn forward, and Will be inclincd to thc side of the bean1 when the drall; is applied to the other end.

'Ihc beznns of cach section of thc harrow mny be united togcther ntthelr rcarends by a number of separate und distinct clamping-bolts, upon which are placed spools 01 cyllnders, as shown, for the purposc of keeping thc bcams apmt. These spools and bolts may bc uscd l'orconnectingtogetherbothcndsof thc beums, or there nmy be an iron crossbar uscd als bhe front end, and the spools used ab the rear end onl y. Where the spools are used thc extension bcyond the front end cf tll0 harrow may bc formed by making the holt considerably longer than is nccessary to mach thpough the two bcnms, and 011 this outer projecting end will be placed a short section of a spool, es shown in Fig. S. 'lhis same projection may also hc formcd by an angular iron cnsting, which is securcd to thc sidc of the harrow, as shown in Fig. 9.

I am well awarc that metal plates have been bolted to the sidcs of solid beams, und that thcsc platcs arc provided With flanges around their edges, as shown in thc patent to J. H. und T. K. Barlcy, Jnl y 2,1878, am] hcrc lay no claim to any such devices. Clhis invention difi'ers l'ro1n such construction in dispensing with such dcvices, andmaking thc beams control thc movcments 0t' the tecth.

Hnving thus describcd n1y invention, I claiml. In a harrow, thc combination of a drafl: l0tl or bar with the sections of the harrow, the chains G, which unitc tl1e sections to the draftrod, und the chain I, which nnites the corncr cf the adjacent section to thc chain G, substantially as shown.

2. In a harrow, the coxnbinntion of thc dmft- 1"0(1, the chains G I, and the diagonal brace 01' chain, which unitcs lhe two scctlons of the harrow together, snbstantially as dcscribcd.

3. In a harrow, the extensions E, runde to projcct beyond the two edgcs 0f the scctions ot' the hzurow, with thc chains G, which are connected to said cxtensions und nnitcthc sections of the har1ow to thc draft-bar, substantially as set fortlx.

4. In a harrow, thc combination, with thc double-flanged bcam, O, of ehe polygonal stopblocks J, und the harrow-tooth clamped thereto and against thc edges ot' thcflanges, which act as stops to thc movement of the blocks, substa-ntlally as specified.

5. In a harrow, thc oombination of a tooth holder with thedouble-flanged beznn, theplate being clzunped thercto and iuscrted betwcen the fiunges cf t;he bcan1 which holds thc platc und tooth in position, substantially as und fo1 thc purpose shown and described.

In testimony that; I claim the'foregoing I have hereunto set; my band this 4th day of J anuary, 1881.
